CAR-SEAT.

Original application filed May 20, 1916,

To all whom it may concern:

Be it known that I, RAYMOND F. STUBBLE- BINE, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have 1nvented certain new and useful Improvements in Car-Seats, of which the following is a specification. v

My invention relates to stationary carseats, and my object is to provide a construction in which the seat-cushion is particularly designed to increase the comfort and to aid in holding the passenger to the seat during rapid travel. To this end, I have devised a seat-cushion which comprises a frame so shaped as to give a top surface to the cushion which gradually curves upwardly from rear to front and provides a desired downward curvature at the front.

edge without the employment of springs. My object is accordingly to provide improvements in seat-cushions of the character referred to. The present application is a division of my application Serial No. 98,714, filed May 20, 1916, for car-seats.

In order that a clearer understanding of my invention may be had, attention is hereby directed to the accompanying drawings forming part of this application and illustrating certain embodiments of my invention. In the drawings Figure 1 is a vertical transverse section through a seat-cushion taken on line 11 of Fig. 2, Fig; 2 is a bottom plan view of the seat-cushion, Fig. 3 is a vertical section taken on line 3--3 of Fig. 1 and Figs. 1 and 5are sectional details showing different forms of slats which may be employed in the seat-cushion.

Referring to the drawings, theseat-cushion 1 is shown to comprise front and rear rails 2 and 3 and transverse ends rails 4;, 4:. These rails are preferably of wood appropriately joined together at their ends as by means of the corner pieces 5. Slats 6, 6 extend across the frame adjacent the end rails 4, 4 and a central supporting'member 7 extends across the frame intermediate slats 6, these transverse members being suitably secured to the front and back rails as by means of dowels 8. The front rail 2 is of greater height than the rear rail 3. A thin steel sheet 9 is placed upon the front and rear rails and the end rails 4:, the latter Specification of Letters Patent.

having their upper surfaces curved downwardly in thevmanner indicated at Fig. 1. The sheet 9 is shaped to the same curvature, so as to prevent a concave seat support hav- 1ng-1ts highest point atthe front edge and the lowest point somewhat in advance of the rear edge. The upper surface of the rear rail is formed on the same curvature as the adjacent portion of sheet 9, while the front rail is curved forwardly and downwardly to form a front edge roll. The upholstery, such as the filling of hair-felt, or the like, 10, and the outer cover 11, which may be of ratan or other suitable material, is placed upon sheet 9, the rear edge of the ratan being bent around the rear rail 3 and secured to the bottom thereof at 12, while the front edge of the ratan is secured to the under side of the front rail 2 at 13, the hairfelt or filling material 10 extending at the frontbeyond the forward edge of the plate 9 and tapering off at the front of rail 2. The center rail which additionally supports plate 9 is, of course, given the same configuration at its upper surface as the end rails 41:. g

The slats used with this construction may be of wood, or of wood with a sheathing of steel, as shown at 14 in Fig. 5, or entirely of steel as is illustrated in Fig. 4. In the latter form the slat preferably is formed as a box-section having an upper channelshaped member 15 and a lower horizontal member 16 having upwardly and downwardly extending alined flanges 17 and 18 contacting the inner surface of the downwardly extending .flange 19 of the top member. The form of slat shown in Fig. 5

is also provided with a downwardly extending'fiange19 formed at one end of the steel sheathing 14:. The slats are preferably formed with looking slots extending longitudinally therethrough, adapted to coact with headed pins extending upwardly from the top surfaces of the transverse supports for the seat, the downwardly extending flanges 19 or 19 being adapted to engage the inner edges of such supporting surfaces to properly aline and secure the seat.

.It is obvious that metal frame members of appropriate design may be used in place of the wooden frame members shown. The concave form given the seat-cushion, as described, is particularly suited to increase the comfort of the occupant of the seat during curve between the middle and rear thereof, a sheet placed on said frame members and shaped to conform thereto, and upholstery secured over said sheet and frame members, 15 substantially as set forth. k
